BELT-FASTENERS.

Specification forming part of Letters Patent No. 222,535, dated December 9, 1879; application filed October 18, 1879.

To all whom it may concern:

Be it known that I, CONRAD W. SAGER, of

Perrysburg, in the county of Miami and State views of the parts of the coupling.

This invention has relation to improvements in fastenersfor endless belts; and the nature of the invention consists in certain novel arrangements of the parts of a detachable fastener, as w1ll be hereinafter more fully set forth.

In the annexed drawings, the letters A A designate the parts of the fastener, which I will describe as follows: The part A is composed of the parallel cross-bars a a and the depressed side barsb b, converging slightly toward each other. The cross-bar a, has projectin g from its under side, partly across the interval between the cross-bars, a short lug, c, (the object of which will be hereinafter shown,) and the bar a is slightly beveled at its edge bounding said slot or interval, as shown at i. The part A is also composed of two cross-bars, c e, and two depressed side bars, ff, that converge toward each other sufficiently to be easily passed between the corresponding bars of the part A, and each provided with a shoulder, g, upon its side, close to the bar 6 aforesaid. This bar is beveled upon its edge next the slot, as shown at t", Fig. 2. The bar 6 of part A projects a short distance beyond the side bar adjacent thereto, thus forming a lug, Z.

The parts A A of the coupling or fastener q are interlocked as follows: The ends of the belts having been secured to the cross-bars e a 'is introduced under the corresponding bar a of part A, the side bars of the former being received between those of the latter until it passes beyond the end of the lug c, the projecting end l of the cross-bar of the part A being introducedinto the slot of part A and passed over the side bar I) of the latter. The sections of the'coupling are then drawn away from each other until the lug 0 passes under the bar 6 of part A, when the interlocking is complete. In this construction the side bars of the part A are between those of part A; consequently there can be no endwise play. The ends of the side bars of section A abut against the shoulders g of the side bars of section A; consequently thereis n0 lengthwise play of said sections; and as the side bars of the said section are under the cross-bar of section A and the lug c of the cross-bar a under the cross-bar, there can be no vertical displacement. The sections, however, readily adapt themselves to the convexity of the pulleys, owing to the edges of the bars 0 abeing bew eled. Thus a complete reliable coupling is had, that may be easily disconnected, if desired, but cannot come apart casually.

What I claim as new, and desire to secure by Letters Patent, is

The belt-fastening consisting of the section A, having the cross-bars a a, converging depressed side bars I), and lug c, projecting from the under side of bar a toward bar a, and the section A, having the cross-bars e e, the depressed converging side bars f f, having shoulders g, and adapted to be received between the side bars b b, and the laterally-projecting lug l at one end of bar e, the whole combined and operating as set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

CONRAD W. SAGER.
